Within Microsoft's windows; instructed.

 Chrome is out of dated.  Click downloading, doesn't downloading to a folder or file. Later you click the arrow link for computer (your ) dowwnload. And find that everyone those time  I follow and did as asked. Then find out upgrading is still awaiting inside the folder. Question One: is that really what is happening?  have it been sitting awaiting me to install.second Question; I read because 13 times, I've downloaded about the Chrome on this computer is out of date. Some instruction about downloading and, installing,and believe not ever complete; correct or incorrect? After the reading. Have 13 icons of the same thing. I click to see if it was the way to install the newer chrome.  Install wasn't the instructions; warning about risk, information about the loggin driver as the relationship for my hard drive disk and informative setup.exe.-next choice run or cancel. Question, should I click run? I am not sure whether the new chrome already installed.
